Generally, application rates consider nutrient volatilization, nutrient availability, method of application of the waste material, as well as cropping system utilized. Another water quality problem that has emerged from anaerobic lagoons is seepage. Seepage from lagoons to surrounding groundwater or surface water resources can pose a threat to human health, as well as toxicity to aquatic life.

Nitrogen is released from microbial decay in the form of ammonium, but can also be immobilized by microbes which take up nitrate and ammonium to satisfy their own requirements. The mobilization or immobilization of nitrogen is dependent upon the amount of N the decomposing material itself provides; insufficient nitrogen released from decaying organic matter will result in the absorption of ammonium and nitrate by the microbes. An excess of N will satisfy the requirements of the microbes and provide a surplus to be released into the soil... ... middle of paper ... ...6-100. Campbell, C.A., V.O. Biederbeck, and F.G. Warder.
This is due to the excessive accumulation of nutrients at a much faster speed caused by human error. Cultural eutrophication happens when surface run-off, that contains nitrates and phosphates, moves from one place to another, ending up in a river or lake. Unfortunately, there are times when these nutrients end up being leached into the groundwater. At times eutrophication may be severe enough that it causes the oxygen in these water bodies to become quite low. The results of this is seen in the harmful effect it has on aquatic wildlife, creating what is referred to as dead zones.
